Publication number: 20190082941Abstract: A camera control unit for an endoscope includes a power supply, an identifying portion, a control portion, and a switch. The power supply generates a required voltage for each of the plurality of various endoscopes expected to be connected to the camera control unit. The identifying portion identifies the required voltage of one of the various endoscope connected to the camera control unit. The control portion controls the power supply in such a manner that power having the required voltage is generated according to an identification result of the identifying portion. The switch is disposed on a power supply path connected to the power supply. The switch is set to alternate between conduction and/or blocking of the power supply path.Type: ApplicationFiled: November 15, 2018Publication date: March 21, 2019Applicant: Olympus CorporationInventors: Nanako Ubayama, Takehide Fujimoto, Hitoshi Komine
